    摘要: Cardioprotective pacing is applied to prevent and/or reduce cardiac injury associated with cardiac catheterization or surgery. Pacing pulses are generated from a pacemaker and delivered through one or more pacing electrodes incorporated onto one or more devices used in the cardiac catheterization or surgery. The pacemaker controls the delivery of the pacing pulses by executing a cardioprotective pacing protocol. In one embodiment, the one or more pacing electrodes are incorporated onto an intravascular ultrasound (IVUS) catheter. In another embodiment, the one or more pacing electrodes are incorporated onto one or more cardiac surgical instruments such as a heart stabilizer and a sternal retractor.

    摘要: An apparatus comprises an implantable cardiac signal sensing circuit, configured to provide a sensed near-field depolarization signal from a ventricle and to provide a sensed a far-field intrinsic atrial signal using a far-field atrial sensing channel, and a controller circuit communicatively coupled to the cardiac signal sensing circuit. The controller circuit includes a P-wave detection module configured to detect an atrial depolarization in the sensed far-field intrinsic atrial signal and a tachyarrhythmia detection module configured to detect an episode of tachyarrhythmia using the sensed near-field depolarization signal and to determine whether the tachyarrhythmia episode is indicative of supraventricular tachycardia (SVT) using the detected atrial depolarization and the sensed near-field depolarization signal.

    摘要: Systems and methods facilitate placement of a lead in or on a patient's heart. At least one reference sensor is positioned at a right heart location of a patient's heart and a cardiac lead apparatus comprising at least one lead apparatus sensor is advanced to a plurality of left heart locations. Using the reference sensor and the lead apparatus sensor, a distance parameter indicative of a distance between the reference and lead apparatus sensors is measured for each of the plurality of left heart locations. Strain or stress estimates are determined for the plurality of left heart locations derived from the distance parameter measurements. Using the strain or stress estimates, a physician perceivable output is produced indicating suitability of the left heart locations as pacing sites.

    摘要: A device and method for delivering electrical stimulation to the heart in order to improve cardiac function in heart failure patients. The stimulation is delivered as high-output pacing in which the stimulation is excitatory and also of sufficient energy to augment myocardial contractility. In order to provide a consistent hemodynamic response, the high-output pacing is optimized by delivering it using different parameter sets, evaluating the hemodynamic response thereto as reflected by one or more measured physiological variables, and selecting the parameter set with the best hemodynamic response.

    摘要: Methods and devices are described for delivering electrical stimulation to the heart in a manner that advantageously redistributes myocardial stress during systole for therapeutic purposes in the treatment of, for example, post-MI and HF patients. Pre-excitation pacing may be applied to deliberately de-stress a particular myocardial region that may be expected to undergo deleterious remodeling, such an the area around a myocardial infarct or a hypertrophying region or to deliberately stress a region remote from the pre-excitation pacing site in order to exert a cardioprotective conditioning effect, similar to the beneficial effects of exercise. Pre-excitation pacing may be advantageously combined with inotropic electrical stimulation applied to the stressed region.
